Dear ZX-VGA-JOY users,

There is a problem in version v1.03. On some computers, ZX-VGA-JOY doesn’t boot well on every power-up.
It is related to the duration of ZX Spectrum reset.
The bug is already fixed, and new version v1.03a will be released in a couple of days because I need to test it well.

Sorry for this inconvenience!

Best wishes
Goran

Although I was busy very much with my ordinary work, I catch some time for retro fun!
I finished the most important things so new version v1.03 is in the testing phase.
I have to test lots of games and demos on a few different computers and make some measurements to make sure that new features and corrections are working properly.
Besides general code optimization, you will get interlaced mode option, VGA 640×480 @50Hz screen mode, partial decoding of page register (with full decoding some demos are not working properly),
lower power consumption and several less noticeable corrections…

Regards Goran
